THE highest proportion of residents who believe their city has quality, affordable housing, good economic opportunities and quality of life.

THE strongest growth of volunteers in the country.

THE highest number of single-person households.

City resident Rebecca Harvey, 26, was not surprised Adelaide was named the most livable city. "I think we are incredibly lucky," She said. "I lived in Sydney for two years before but I moved back home and I love it. We have a great culture."

Social analyst David Chalke said Adelaide had the facilities of a large city without the expense and congestion.

"What makes Adelaide pleasant to live in is it has all the features of a big city with an international airport, a decent arts community, both industry and commerce and affordable housing and yet it is not so big that you cannot get around or is terribly expensive," Mr Chalke said.

Premier Jay Weatherill said a redeveloped Adelaide Oval and riverbank, upgraded laneways with small bars and flexible shopping hours would cement Adelaide's reputation as one of the world's great small cities.

"Adelaide is consistently recognised by others as a great place to live," he said.

Lord Mayor Stephen Yarwood said the City Council would ensure Adelaide remained the most livable city in the country.

"But there are so many things we must do to future-proof our city and make it even more livable, such as providing housing diversity and greater transport choice," he said.
